            Bug ID: 25701
           Summary: Means to limit considered debug info
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org
          Reporter: vries at gcc dot gnu.org
  Target Milestone: ---

Say I want to debug an executable from a package on my distro, which uses
shared libraries which come from the same or other packages.

I can control what debug information gdb has available by installing and
de-installing corresponding debug packages.

I can also do "set debug-file-directory" which will disable all debug packages
in one go, without having to de-install any package.

It would be convenient to be able to limit the scope of considered debug-info
somehow, without having to install or de-install debug info, and in a more
precise way than disabling all debug packages.

You can set auto-solib-add off, then use sharedlibrary to selectively load
symbols.

Ah, yes, that sounds close enough to what I was looking for, thanks for the
pointer.

I was also thinking about being able to do the same for executables, and it
seems that using exec-file instead of file is the equivalent there.

Playing around with the two options, I noticed that indeed no info is read at
all, not even the minimal symbol info.

I was thinking more about avoiding parsing dwarf (to speed up debugging) than
avoiding minimal symbols (which are processed relatively quickly), so perhaps
we can make a mode that we at least read minimal symbols, such that f.i. I can
still set a breakpoint in main.

But for now, that's not my immediate concern, so I'll mark this one as
resolved-worksforme.
